FRANK-A. BONENBERGER, OF LOUISVILLE, KENTUCKY.

COIN-CONTROLLED MIACI-IINE.

To all whom it may concern:

Be it known that I, FRANK A. BoNEN- BERGER, a citizen of the UnitedStates of America, residing at Louisville,in the county of Jefferson andState of Kentucky, have invented certain new and useful Improvements inCoin-Controlled Machines, of which the following is a specification.

This invention relates to coin-controlled devices and has specialreference to a coincontrolled machine for vending paper towels and thelike.

One important object of the invention is to improve and simplify thegeneral construction of devices of this character.

A second important object of the invention is to provide an improvedform of coinreceiving driving gear for such apparatus.

A third important object of the invention is to provide an improved feedand cut-off arrangement for use in connection with such an apparatus.

lVith the above and other objects in view as will be hereinafterapparent, the invention consists in general of certain novelarrangements of details and combinations of parts hereinafter fullydescribed, illustrated in the accompanying drawings and specificallyclaimed.

In the accompanying drawings, like charcters of reference indicate likeparts in the several views, and

Figure 1 is a perspective view of the eX- terior of a towel bendingapparatus constructed in accordance with this invention.

Fig. 2 is a vertical transverse section through the device.

Fig. 3 is a section on the line 3-3 of Fig. 2.

Fig. 1 is a detailed perspective view of a portion of the driving gear.

Fig. 5 is a similar view showing the com block removed from the drivinggear.

Fig. 6 is a similar view of the stop for the driving gear.

In the embodiment of the invention here in illustrated there is provideda casing 10 having a hinged door 11, the latter being equipped with theusual lock the key hole of which is indicated at 12.

Extending through this casing is an axle 13 having on its outer end acrank-handle it while on its inner end there is provided a main drivinggear 15 which has on the face next the casing one or more pockets 16opening peripherally through the gear and having located therein acoin-receivlng block 17 Specification of Letters Patent.

provided with a coin recess 18. This block in each instance is securedin the pocket by suitable screws 19. Thus when a block becomes worn itmay be readily replaced without the necessity of replacing the entiregear and blocks may be changed from time to time to accommodatedifferent sizes and consequent values of coins. In the side of thecasing adjacent the upper side of the peripheral gear 16 is a recess 20wherein is mounted a stop having a head 21 corresponding in shape andsize to the recess 18 and having its upper edge beveled as at 22. Thisstep is provided with a stem 23 which is surrounded by a spring 2 1 sothat the stop is normally pressed'outward to enter the recess 18. l/Vhenin this position the stop terminates rotations of the gear 15. On theface of the casing and extending therefrom there is provided acoin-receiving slot 25 which terminates inwardly in a chute 26 the lowerend of which stops above the stop 21 so that when a coin is dropped downthis chute it will come to rest on the beveled edge 23 of the stop 21.Above this end of the chute is provided a guide 27 wherein operates avertical plunger 28 actuated by a lever 29 the handle of which projectsthrough a slot 30 in the face of the casing. This lever and plunger arenormally kept raised by a suitable spring 31. By means of thisarrangement when a coin is dropped down the chute and the lever 29depressed the coin is forced against the beveled edge 23 of the stop 21and thus causes the head of the stop to move inward, the coin passinginto the recess 18 previously occupied by the stop. The crank 14: cannow be manipulated to rotate the gear 15 and if there be but one stop asin the case of selling an article for a single coin such as a cent acomplete revolution may be effected and when completed further movementwill be terminated by the reentry of the stop into the recess 18.However two or more recesses may be used so that the towel or otherarticle may be sold for two or more cents for instance. In this casewhen a partial revolution of the wheel has been effected the stop willagain check the motion and the complete revolution can be effected byagain dropping a coin.

At each side of the casing there is provided a bearing, one of thesehearings being shown at 32 and the other not being shown. Extendingbetween these bearings is a shaft 33 whereon is mounted a roller 34 ofpaper .towels or the like.

The paper from this roller passes over small rollers 35 so that itpasses immediately back of a glazed window 36 in the front of thepockets and can there be observed. From the lowermost of these smallrollers 35 the paper passes between two rubber rollers 37 and 38, theroller 37 being held in fixed bearings while the roller 38 has a limitedlateral movement and is pressed against the roller 37 by means of a yoke39 and spring 40 as clearly shown in Fig. 2. The roller 37 is moreoverprovided with gear teeth 41 which mesh with the teeth of the gear 15 sothat when the latter is rotated the roller will be rotated and the paperwill be fed downward between said rollers 37 and 38.

At 42 is a paper chute which terminates at the bottom in a slot 43opening through the bottom of the casing 10. At one side of this slot isa metallic plate 44 while on the other side'is a movable metallic plate45 which is carried at each end on the lower end of a bell crank lever46. This lever is normally held in such position that the plate 45presses towel against the plate 44 thus enabling the paper to be tornoff sharply at this point, this pressure being effected by a spring 48.However, it would be impossible to, feed the paper through the slot withthe plates 44 and 45 pressed together and in order to release the plate45 from the plate 44 there is mounted on the gear 15 a cam 49 againstwhich the remaining end of the bell crank lever 46 engages, this cam isso shaped thatwhenever the feeding of the paper has been completed theend of the lever engaging the cam rises and the plate 45 moves towardthe plate 44 but whenever the gear 15 is rotated the end of the leverengaging the cam is depressed and the plate 45 moves away from the plate44.

The usual removable coin receptacle 50 is provided. 7

In order to hold the paper roller against wrinkling a suitable springand presser bar indicated at 51 is provided.

' In general operation the coin is deposited, the lever 29 depressed,and the crank 14 rotated. This causes rotation of the roller 37 andmovement of the plate 45 away from the plate 44. The paper is thus feddownward from the bottom of the casing until the proper amount haspassed through. At this time the parts will resume their originalposition and the paper can be torn ofi'.

In order to prevent backward rotation is claimed as new, is

1. In a devlce of the kmd described, a rotatable wheel having a pocketat its periphery, a member fitting said pocket removably and havlng arecess thereln adapted to recelve and hold a com, and means to hold saidmember releasably in position in said pocket.

2. In a device of the kind described, a delivery mechanism driving wheelhaving a coin-receiving recess in one face thereof and opening outwardlyof the periphery, a spring pressed stop normally fitting said recess tohold the wheel from rotation, said stop having a beveledportion disposedadjacent the periphery, means to rotate the wheel, and means to force acoin against the beveled portion of the stop and into said recesswhereby the stop is forced outward and the wheel freed for revolution.

'3. In a device of the kind described, a delivery mechanism drivingwheel arranged to be revolved and having a coin receiving recess in oneface thereof, a spring pressed stop normally fitting said recess to holdthe wheel from rotation, said stop and wheel being constructed andarranged to provide a wedge shaped pocket at one end of the stop,

a coin delivery chute leading to the wedge shaped pocket, and means'toforce a coin from said chute into said pocket and thereby causeretraction of the stop recess.

4. In a device of the kind described, a delivery mechanism driving wheelarranged to be revolved and having a coin receiving recess in one facethereof, a spring pressed from the stop normally fitting said recess tohold the wheel from rotation, said stop and wheel be ing constructed andarranged to provide a wedge shaped pocket at one end of the stop, a coindelivery chute leading to the wedge shaped pocket, a plunger movabletoward and from said recess and engageable with'a coin in positionopposite to the pocket, and a manually operable lever controlling saidplunger, said plunger and lever constituting means to force a coinbetween the stop and wheel whereby to'cause retraction of the stop fromthe recess.

In testimony whereof I affiX my signature.
